PART OF YOUR GREEN BUILDING SOLUTION

     Keystone Industries Window & Screen Systems, Inc. was founded in 1989 by a father & son team, Michael DeRosa Jr. & Sr., who have collectively worked in the commercial window business for 42 years. The DeRosas reached an agreement with the Alsides to purchase their aluminum commercial window lines at which time capital was raised by family & friends who believed in the ability of the management team. Keystone started out in leased manufacturing space in an incubator for industry in New Castle, Pennsylvania, their home town.

     As business grew, a larger facility was purchased in New Castle in 1991 which is where the company is presently located. Today approximately 102 people are employed there.

     Keystone's primary market in 1989 was public housing but has quickly expanded. Our company now provides window & screen systems for the college and university market, as well as military housing, K-12 schools, hospitals, and office buildings. The addition of our flagship KI7000 SYSTEM window line has allowed us to explore unlimited possibilities in the fenestration industry. Keystone reaches it's customers through a network of experienced, independent architectural representatives.

     The Keystone management team remains focused on building a quality commercial product that continually develops into the most efficient & maintenance-free window & screen product on the market today. We believe in the concept to "do what you do best & continue to improve". It is this idea that has allowed us experience an annual growth in sales in excess of industry standards.

     While expanding our areas of expertise is an ongoing process, controlled growth is always a primary concern. The diversity of our management team sets us apart from the rest of the window industry & we remain confident in our ability to expand our products without jeopardizing the quality customers have come to expect from this aggressive little company called Keystone Industries.
